Optimization of plate heat exchangers with intermittent ridges
Original language description
This study deals with a plate heat exchanger with intermittent ridges. We used software Fluent and so-called ?user defined deforming? to deform computational mesh and create various shapes of heat exchange surfaces with different count of ridges and different count of set-offs. The intention of the set-offs is to discompose boundary layer inside channels, which are created by ridges, mix the temperature field and thus intensify the heat transfer. We used previously formulated objective function, which is a linear combination of efficiency and pressure loss, and a simple local method to optimize the shape of the heat exchange surface for required pressure loss. It was found that the objective function surface is monotone and unimodal, but it is not smooth. The global optimums were identified and it was shown that the optimal wall shape has no set-off for low pressure losses. The optimal count of ridges and optimal count of set-offs rise with higher required pressure loss. It was proved
